he he he ... i can tell you the history
that is a classic NAK with the classic mistakes sweet sounding amplifier with some cooling issues and obviously not a party animal still distortion figures are pretty low and generally is a nice class AB amp
Mistake is that due to size requirements that filter capacitors are placed horizontally with he well known end of life issue but the worst from all is that the choice of capacitors for the rest of the circuit is horrible and expect them all to be very dead .
If you also have the matching preamp no questions asked all the capacitors inside are dead as we speak and need to be replaced
As about the amp NaK had stability and power issues and bad feedback from costumers that expected a NAk to be a party animal and eventually blow the speakers
Nak Had to add a protection circuit to the amp afterwards
as about the preamp i will say that it was too complicated to sound clean .... stage by stage well designed though
Kind regards
